In response to a large growing number of spam calls to mobile phones, many carriers have created tools to identify and block spam calls. Unfortunately, these tools aren’t perfect and it can result in a legitimate business phone number incorrectly marked by scam ID technology. Some people may report your number without answering the phone. If this happens enough, your number will be marked as 'Spam' or 'Scam Likely'.

If outbound calls from your Ring.io company or personal number are being flagged as 'Spam' or 'Scam Likely', you're not alone! This has affected customers across all major carriers but Ring.io has measures in place to combat this. Below are the most common reasons for why a number will be flagged are listed below.


1. The number has been reported as Spam Risk
2. Carriers have flagged the number for frequent dialing
3. Low Attestation Rating

4. Inconsistent volume of calls from the same number
5. Calls of short duration, typically under five to ten seconds

6. Calls that are sent immediately to voicemail

7. Number is being flagged
